Dorsal surface without punctuation; meso- and metepisternum, and metasternum at sides more densely and strongly punctate than proepisternum and prosternum at sides; abdominal ventrites 1���5 punctate at sides and submedially, ventrite 6 punctate at apex. Head. Less than half as wide as pronotum (Table 2). Mentum tooth short, truncate, with paramedial border distinct (Fig. 6F). Thorax. Pronotum (Fig. 6E) with sides barely rounded toward posterior angles (PW /PB: 1.02���1.06); maximum width in posterior fifth; laterobasal impressions indistinct; base slightly sinuate; anterior angles rounded, weakly projected. Prosternum with median longitudinal sulcus shallow but distinct, deeper than in species from ��� cribristernis ��� group; prosternal process elliptic, with subpointed apex (Fig. 6G). Metepisternum longer than wide (MA/ MM: 0.82���0.87), with lateral margin convex, coadunation with epipleuron short, located near middle (Fig. 6B). Elytra. Apical sinuation strong, well defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola quite reduced, shallowly punctate, much less impressed than other striae; striae punctate. Intervals 1���6 flat, 7 subconvex, 8 more convex than other medial intervals. Legs.

Protarsomeres 1���3 of male moderately dilated, with second segment slightly wider than long (W/Lp2: 1.19���1.25). Male genitalia. Median lobe (Figs 7A, B) with basal bulb relatively short, bent ventrally; angle between basal bulb and shaft obtuse; shaft long, slightly swollen medially; apex short, straight; apical lamella short, rounded, with right margin curved to left. Female genitalia. Basal gonocoxite with two large and several minute lateroapical setae. Apical gonocoxite elongate, with two dorsolateral ensiform setae different in size, large dorsomedial ensiform seta near base, and nematiform setae at apex (Fig. 7C). Bursa copulatrix without sclerite; spermatheca moderately long, differentiated, with seminal canal long and narrow, and receptaculum short and wide, twisted apically; spermathecal gland connected near apical fifth of seminal canal (Fig. 7D). Distribution. Malaysia (Kuala Lumpur, Sarawak, Sabah), Brunei, Indonesia (Sumatra, Borneo). New species for Brunei and Indonesia. Bionomics. Labels data indicate that specimens were collected most commonly at light. In the states of Sarawak and Sabah, Malaysia, they were caught near banks of large rivers (Sarawak River, Rajang River, Baram River, and Padas River). Like P. cribristernis, this species inhabits areas with a wide spectrum of altitude; for instance, in Sabah State, it was gathered near sea level (Tawau) and at up to 2000 m (Mount Trus Madi). ��� ampliusculus ��� species group Diagnosis. The only member of this species group possesses the following two peculiarities: (1) large and very broad body; and (2) very long metepisternum. Pseudoodes ampliusculus shares with members of the ��� cribristernis ��� group a bursa copulatrix with dorsal sclerite. The spermatheca of this species is slightly differentiated as in P. rambouseki but it is less elongate (see ���Diagnosis��� under ��� rambouseki ��� species group). 5. Pseudoodes ampliusculus sp. n. (Figs 8 A���F, Table 2) Type material. Holotype ♀, ���[Hainan Jianfengling N.R., Mingfenggu Valley], 2011���V���11 ~23 950���1000 m [Bi Wenxuan] leg. [w, h/p] // China, Hainan, Jiangfengling, Mingfenggu, 2011.5.21 950���1000m, BI Wenxuan collector [w, p]��� (IZAS). Paratypes, two females: ��� TONKIN Hoa-Binh VII 40 leg. A. de Cooman [r, h/p]��� (IZAS); ���Thailand Khao Sok National Park 8.90844 98.53247 74m 2018.4.17 ���24 Li Chao [w, p]��� (NMNHS). TME: 3 specimens. TGE: 1♀. Diagnosis. Members of this species are readily distinguished from all other representatives of Pseudoodes by the longest metepisternum (MA/ MM ���0.81) and widest body (BW> 6.10 mm, Table 2). In addition, P. ampliusculus can be differentiated from P. subcoriaceus, which is the only other member of the genus with body size more than 15 mm, by PW /HW>2.10 and PW /PA>1.90; from both P. cribristernis and P. vicarius by its larger size; and from P. coelestinus by its black color of dorsum and larger size. The new species differs from taxa of the ��� rambouseki ��� group in its larger size, more than 15 mm, greater values of PW / PL and EL/ PL, and metepisternum longer than wide (MA/ MM Description. Habitus. Specimens of large size (BL: 15.5���15.7 mm, BW: 6.20���6.65 mm), with ovate and subconvex body (Fig. 8A). Ratios and measurements. See Table 2. Color and luster. Body black; antennae, palpi and tarsomeres rufopiceous, remaining parts of legs piceous. Integument moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation (in holotype only, posterolateral parts of pronotum, with large, moderately deep punctures extending laterally to anterior third); meso- and metepisternum entirely, prosternum, proepisternum, and metasternum at sides finely and densely punctate; abdominal ventrites 1���5 finely rugose and punctate at sides, ventrite 6 punctate at apex. Head. Less than half as wide as pronotum (Table 2). Mentum tooth truncate, with distinct paramedial border (Fig. 8B). Thorax. Pronotum with sides slightly rounded toward posterior angles (PW /PB: 1.04���1.05); maximum width at posterior third; laterobasal impressions very faint, almost indistinct; base moderately sinuate; anterior angles widely rounded, barely projected. Prosternum with median longitudinal sulcus moderately distinct; prosternal process elliptic, with rounded apex (Fig. 8C). Metepisternum longer than wide (MA/ MM: 0.78���0.81), with lateral margin straight posteriorly, coadunation with epipleuron long, located anteriorly (Fig. 8D). Elytra. Apical sinuation moderate, well-defined. Basal margin distinct laterally, forming a small denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola distinct, less impressed than other striae; striola punctate, striae 1���4 punctate in basal sixth, striae 5���8 impunctate. Intervals 1���4 flat, 5���7 subconvex, 8 more convex than intervals 5-7. Legs. Metacoxal basal sulcus extended to lateral third. Male genitalia. Unknown. Female genitalia. Basal gonocoxite with four or five lateroapical setae situated in line. Apical gonocoxite stout, with very tiny dorsolateral ensiform setae, dorsomedial ensiform seta at base, and nematiform setae equidistant from middle and apex (Fig. 8E). Bursa copulatrix with a large dorsal sclerite; spermatheca moderately long, less differentiated than in species of ��� cribristernis ��� group, with receptaculum twisted apically; spermathecal gland connected in apical third of seminal canal (Fig. 8F). Etymology. The specific epithet, ampliusculus is Latin for ���fairly large, considerable���, to stress the large size of body. Distribution. China (Hainan Province), Vietnam (H��a B��nh Province), Thailand (Surat Thani Province). Bionomics. The place in Mingfenggu where the holotype was caught is wet, and located very close to a lake. The specimen from the Khao Sok National Park, Thailand, was collected by light trap, located close to a pond. ��� rambouseki ��� species group Diagnosis. The species group includes five wingless species that possess the following synapomorphies: (1) metepisternum one-and-a-half times or more wider than long; (2) extraordinarily elongate spermatheca; and (3) apical gonocoxite short, subtriangular, with dorsomedial ensiform seta situated near the middle or equidistant from the middle and the base. In addition, the species from the ��� rambouseki ��� group have the anterior angles of pronotum more projected and pointed, as well as the parascutellar stria more obliterated than in other representatives of the genus (except P. coelestinus which also has an obliterated parascutellar stria). Further, three species (P. hunanensis, P. leigongshanicus, and P. rambouseki) have a metatrochanter more or less pointed at the apex (Figs 10E, 11D, 12H). All five representatives are wingless, with fused elytra and reduced metathoracic wings. Notes. Pseudoodes hunanensis and P. leigonshanicus (supposedly also P. emeishanicus and P. tianlinenis whose females are still unknown) have very long, undifferentiated spermatheca. On the other hand, P. rambouseki has a spermatheca also quite long but slightly differentiated (like P. ampliusculus) into a seminal canal and a receptaculum. Tendencies to slightly differentiated and undifferentiated spermatheca are aberrant conditions within Pseudoodes. They occur in species from the ��� ampliusculus ��� and ��� rambouseki ��� groups, and are considered a reversal (loss of derived trait present in the common ancestor) due to considerable lenghtening of the apical part of spermatheca (i.e., receptaculum). Similarly, there are two kinds of attachment of the spermathecal gland to spermatheca among species of the ��� rambouseki ��� group, each linked, respectively, to the above mentioned two kinds of spermatheca. Pseudoodes rambouseki has a spermathecal gland attached at the apical third of spermatheca while P. hunanensis and P. leigongshanicus have the spermathecal gland connected at the proximal half of the seminal canal. Likely the species of this group derived from a common ancestor (supposed form close to P. cribristernis and/or P. ampliusculus) via isolation in the high mountainous areas of south and southwest China. Two groups are distinct: (1) P. rambouseki, having bursa copulatrix with a small dorsal sclerite, spermathecal gland attached at apical third of seminal canal, apical lamella of median lobe narrow, bent to left and rounded at tip, male mesotibia considerably curved and dilated distally, male protarsomere 2 very broad, and MA/ MM relatively low; and (2) P. hunanensis and P. leigongshanicus, having bursa copulatrix without sclerite, spermathecal gland attached at middle of seminal canal, apical lamella of median lobe wide, straight and more or less pointed at tip, male mesotibia almost straight, slightly dilated distally, male protarsomere 2 moderately broadened, and MA/ MM higher. Though females of P. emeishanicus and P. tianlinensis are unknown, judging from the structure of the median lobe (apical lamella similar to that of the two species from Hunan and Guizhou) and less broadened male protarsomere 2, we believe these species belong to the second group. 6. Pseudoodes emeishanicus sp. n. (Figs 9 A���G, Table 2) Type material. Holotype ♂, somewhat in teneral condition, 2011 VIII 21 D [day], 1400m Huang Hao leg., Inst. of Zoology, CAS, Sichuan, Emeishan Xixinsuo Temple [w, p] // China, Sichuan, Emeishan, Xixinsuo, 1400m, 2011.8.21 D HUANG Hao collector, Institute of Zool., CAS [w, p] (IZAS). TME: 1 specimen. TGE: 1♂. Diagnosis. This species is separated from other members of the species group by its shorter pronotum (PW / PL>1.65), with the least pointed anterior angles, shaft of median lobe long and narrower (Fig. 9F) and male protarsomere 2 barely longer than wide (W/Lp2: 1.13). The species is most similar to P. tianlinensis but the latter species has anterior angles of pronotum more distinctly pointed, shaft of median lobe broader (Fig. 13G) and male protarsomere 2 distinctly longer than wide (W/Lp2: 1.26). Description. Habitus. Specimens of moderate size (BL: 13 mm, BW: 5.2 mm), with ovate, subconvex body (Fig. 9A). Ratios and measurements. See Table 2. Color and luster. Body dark brown, appendages rufous. Integument moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation; prosternum and metasternum at sides, and metepisternum moderately punctate; pro- and mesoepisternum nearly smooth; abdominal ventrites punctate at sides. Head. About half as wide as pronotum (Table 2). Mentum tooth with apex truncate, with distinct paramedial border (Fig. 9C). Thorax. Pronotum (Fig. 9B) with sides slightly rounded toward posterior angles (PW /PB: 1.06); maximum width in posterior third; laterobasal impressions shallow; base nearly straight; anterior angles rounded, moderately projected. Prosternum with median longitudinal sulcus distinct, deeper and located more posteriad than in P. tianlinensis; prosternal process elliptic, more narrowly rounded apically than in other species of ��� rambouseki ��� group except P. tianlinensis (Fig. 9D). Metepisternum significantly wider than long (MA/ MM: 1.53), with lateral margin convex, coadunation with epipleuron short, located anteriorly (Fig. 9E). Elytra. Apical sinuation weak, poorly defined. Basal margin distinct laterally, not forming distinct denticle at shoulder, disappearing medially at level between striae 2 and 3. Parascutellar striola distinct, but shallow, punctiform, less impressed than other striae; striae 1���3 superficially punctate anteriorly, remaining striae impunctate. Intervals 1���7 subconvex, interval 8 appreciably more convex than others. Legs. Metacoxal basal sulcus reduced at side, barely reaching lateral third. Male mesotibia slightly dilated distally. Protarsomeres 1���3 of male moderately dilated, with second tarsomere scarcely wider than long (W/Lp2: 1.13). Male genitalia. Median lobe (F
